扇贝的养殖环境及其体内的细菌学分析

自1992年9月～1994年11月，对青岛胶州湾养殖的扇贝及环境中的细菌组成和某些生态学特性进行了调查。养殖区表层海水中异养菌和弧菌平均数各波动于（21．2～39．7）×102／cm3和（7．3～19．2）×102／cm3之间。其中1号和4号站位的菌数比其它越位都高，这和它们靠近码头，受到附近的排水污染有关。在扇贝的消化盲囊和性腺内也分离到异养菌和弧菌，分别为103～105个g和103～105个／g。这些细菌可能因扇贝遇到环境改变防御能力下降时，扩散到其它器官并大量繁殖，因而造成感染而死亡。从对分离菌的药物敏感试验结果看，近年一些菌株对原来敏感的药物产生了抗药性，如四环索和链霉素，今后在育苗过程中避免滥用抗菌药物是十分重要的。

Geophysiology and Parahistology of the Interactions of Organisms with the Environment*

Abstract. Ecology and Global Ecology (GE) are terms by which the relations between the organism (or living matter as a whole) and the environment (or Earth as a whole) have been treated for almost a century. Geophysiology and Parahistology (PH) are terms slowly replacing older scientific thoughts jointly with an increasing number of modifications and alterations of the Darwinian Evolution (DE) concept. Somehow Geophysiology and Parahistology seem to describe evolution in a non-Darwinian domain. According to V.I. Vernadsky (1929,1930,1988) - the great Russian naturalist and biogeochemist - the biogeochemical processes on Earth are controlled by the force of living matter rather than by species associations developing in and with individual ecosystems as expressed by darwinian evolutionary terms. He also claimed that Goethe was incorrectly regarded as a predecessor of DE by some authors (including Darwin) and that “Natur” (nature) and “Lebendige Natur” (the totality of creatures) are two very different things for Goethe. Detailed analyses of microbial mat systems in the German Wadden Sea and in artificial hypersaline WInogradsky columns have shown that the totality of creatures and matter around them i.e., the “lebendige Natur”sensu Goethe or “living matter”sensu Vernadsky of such environments control to a considerable extent the structure, stability. and (geo-)morphology of sediments and thereby the geological structure of the living Earth. These structures do not follow the rules of sedimentation formulated by the laws of Stokes They represent growth structures (Aufwuchs), whose physics and dynamics are controlled by complex fractal systems. The factors controlling the ultimate shape and stabilisation potential of the eventually resulting rocks and fossils are comparable to tissue development in macroorganisms. Also, certain microbial associations in the sub-recent and in the fossil record may be compared to metazoan tissues. Chemical gradients in the sedimentary column, regulated by the interplay of living matter and sluggish (slow-reactive to non-reactive) compounds, combine to create a pattern of porosity and structure of the resulting deposits that clearly indicates microbial influences and especially those of extracellular polymeric substances on the morphology and texture. The combined effects of microbiota or living matter on the sedimentary record are described as parahistology of sediments in analogy of the histology of tissue on a geological scale. This conceptual living tissue made up of microbially generated rocks and ore deposits cycled through metabolic processes and forced into tissue-like structures by microbial biofilms and mats may extend down to the upper mantle of Earth and far up into the stratosphere when Earth is regarded as a living entity over geological periods. We may have to conceive Earth as a living specimen, which is breathing at a frequency of thousands of years instead of the normal physiological breathing rate of man or an insect. Macroorganisms in all terrestrial systems represent the transport and logistic media, which, however, utterly depend on myriads of intra-, inter-, and extracellular microbial symbiotic partners.     

以Ba为指标反演海洋古生产力的研究进展

海洋沉积物中的生源Ba通量与有机碳通量有着惊人的相关性，因此Ba很适合作为古生产力的指标。概述了Ba与生产力的相关性原理．对反演过程中3个主要影响因子(沉积环境、海水中的Ba浓度、沉积物堆积速率)进行了探讨．分析了计算模型并对模型发展方向作了预测。认为生源Ba形成机制和沉积环境中干扰因素扣除将是今后研究的重点．指出在我国开展以Ba为指标的古生产力研究对古海洋生态环境研究有重要意义。     

冲绳海槽北部表层沉积物中底栖有孔虫分布及其与海洋环境的关系

对1999年6月采自冲绳海槽北部的62个表层沉积物样品进行了底栖有孔虫分析。研究表明，该区属种多为中外陆架和上部陆坡常见底栖有孔虫，其中Cibicides pseudoungerianus在研究区域内广泛分布。底栖有孔虫群落明显受研究区水团的制约，该区底栖有孔虫Q型因子分析反映的4个组合分别对应不同的水团影响：组合1以Cibicides pseudoungerianus、Uvigerina sp.、Ammonia ketienziensis、Textularia pseudocarinata为主，代表陆架混合水团影响环境；组合2以Uvigerina peregrina、Beregrina、Bulimina mexicana、Bulimina submarginata、Globocassidulina subglobosa为主，代表黑潮暖流中层水影响下的环境；组合3以喜营养分子Bulimina marginata和Bolivina robusta为主，代表冷涡沉积和上升流沉积区的环境；组合4以Cibicides pseudoungerianus、Globocassidulina subglobosa为主，代表了对马暖流水团影响下的环境，其中水团的氧含量水平和营养状况是影响底栖有孔虫组合变化的主要因素。底栖有孔虫的丰度从西往东依次出现两个丰度高值带，一个位于研究区西部100—140m水深的陆架区，另一个位于400—600m水深的上陆坡，后者可能反映了冲绳海槽大陆坡普遍发育的陆坡上升流现象。

Population dynamics of Callichirus major (Say, 1818) (Crustacea, Thalassinidea) on a beach in northeastern Brazil

We describe the structure, reproductive cycle, fecundity, growth, and mortality of a harvested population of the ghost shrimp Callichirus major. Samples were collected at monthly intervals from September 1999 to October 2000 on an urban sandy beach (08°11′S 34°55′W) in northeastern Brazil. During this period the sex ratio did not differ significantly from 1:1 (0.98 M: 1 F). Minimum and maximum sizes of the Dorsal Oval were 2.59 and 12.19 mm for males and 4.46 and 12.62 mm for females, respectively. Ovigerous females were found throughout the period, except between August and September 2000. Maximum lifespan was estimated as 3.3 and 3.4 years for females and males, respectively. This northeastern population differed from others previously studied in southern and southeastern Brazil, in regard to sex ratio, maximum attained size, maturation size, period and duration of the reproductive cycle, and fecundity. We interpret these regional differences as evidence for over-fishing at the study site, and suggest that large-scale management plans for callianassid populations should use regional population parameters.     

区域海洋地质数据库建设纲要

区域海洋地质数据库是中国地质调查局基础数据库的一个重要组成部分，是实现地质调查基础性与公益性战略部署的依托。根据区域海洋地质数据库建设的目标与任务，在数据结构和实施步骤等方面进行了初步研究。区域海洋地质数据库及其管理信息系统适合采取基于Web系统的三层体系结构，在数据构成上亦分为区域海洋地质调查原始资料与成果资料，其中元数据库的建设对数据库的应用非常重要，用户可以通过元数据了解数据的存在性、适宜性、有效性等，确定数据的使用方法，因此，元数据库的建设应采用国际已经普遍认可的ISO/TC211发布的ISO19115空间元数据标准。
